Cooling System Flushing; Coolant Reserve Tank Removal/Installation - CF MOTO CF400-A 2017 Service Manual

Cooling System Flushing

lates rust, scale, and lime in the water jacket and
radiator. When this accumulation is suspected or
observed, flush the cooling system. If this accumu-
lation is not removed, it will clog up the water
passage and considerable reduce the effi ciency of
the cooling system.
ŸDrain the cooling system (see Coolant Change in
the Periodic Maintenance chapter).
ŸFill the cooling system with fresh water mixed with
a fl ushing compound.
